1. Description of code files: 

1.1 Data Clean:

- usa_00132.do takes the raw IPUMS ACS data and creates the master working data file

- var_lables.do and var_lables2.do contain variable labels

- misc_bpl_recode.do aggregates countries of origin to regions of origin

1.2 Display Items:

- fee_waivers_fig1.do creates figure 1

- fee_waivers_fig3.do creates figure 3

- fee_waivers.do creates figure 2 and figure a1, tables A1, A2, A3, A4, A5, A6, A7, A9
in the online SI appendix

- fee_waivers_robustness.do creates table A8 in the online SI appendix

- nnyFeeWaiverTable_v2. do creates table A10 in the online SI appendix


2. Description of data files:

- usa_00132.dta - master working data file

- povertyGuidelines.dta - poverty guidelines thresholds

- isp.dta - state level internet service providers data from National Immigration Legal Services Directory

- local_controls.dta - state-year level characteristics from the ACS

 - NNYFeeWaiverDataForReplication_anon.dta - data from Naturalize New York project. Note that for privacy concerns, we have aggregated two variables (age and years on green card) into quartile values. This implies that Table A10 will not be perfectly replicated.
